Influence of Oxygen on the Thermal Decomposition ... C4F7N (fluorinated nitrile) gas mixture has been recognized as the most potential substitute gas to SF6 used in gas-insulated equipment. In this paper, we explored the thermal stability and decomposition properties of the C4F7N–N2–O2 gas mixture. The influence mechanism of oxygen content and temperature on the byproduct generation was obtained and analyzed.
